You think probable to Dimitri Mendeleev.
Probable you think to the periodic table of Mendeleev.
the periodic table of elements In this table, elements having similar chemical properties are stacked up. The chemical properties are determined by how many free bonds an atom has open, which is related to how many electrons are in that element's outer shell.
The Russian, Dmitri Mendeleev's periodic table became available to the scientific community vi publication in 1869 and he is generally credited with its "creation"
The reason that Mendeleev didn't make any predictions about the gases was that these gases were not even discovered yet, therefore it was impossible for Mendeleev to make predictions.----Dmitri Mendeleev made his predictions on what would fill the gaps on his far from perfect periodic table. He predicted their sizes, weights, appearances, etc.I think the reason he didn't make predictions is because noble gases are not visible, and weightless.-------------------------------Mendeleev couldn't predict the noble gases' properties because their existence wasn't known, as implied above.Argon, a noble gas, was noticed twenty-five years later by John William Strutt and Sir William Ramsey (the names are not really important).It doesn't matter that the elements weren't discovered. That's the whole point of arranging the elements. To PREDICT the properties of the missing/unknown ones.
Atomic mass in a 'periodic' way Hope this helps :p

I suppose that you think to chemical elements, not to compounds. Dimitri Mendeleev is credited for the creation of the periodic table of elements.
He did order it in the periodic table, but i think what your looking for is that he arranged it in order of increasing Atomic mass
Yes, it is true; this is the fundamental principle of the periodic table of Mendeleev.
At that time, scientists knew some of the properties of more than 60 elements. However, no one had organized the elements according to these properties; making it harder for scientists to understand how elements interact with each other.

Lothar Meyer (1864) and John Newlands (1865) both proposed tables that organized elements according to periodic properties. History Most people think Mendeleev invented the modern periodic table.
he noted gaps in the table, and predicted that as of yet unknown elements existed with properties appropriate to fill those gaps.
I think that was Dmitri Mendeleev way back in 1869.
